Study on the microstructural variation and fatigue performance of microplasma arc welded thin 316L sheet

Welding is a venerable and reliable fabricating technique to integrate materials into complex geometry desired for various industrial applications. However, localized heat concentration leading to microstructural variations can deteriorate the fatigue life of welded components. The present study explains tensile and high cycle fatigue performance of microplasma arc welded 316L SS thin sheet (0.5 mm thickness) material. The square butt joint configuration with a single pass weld was achieved for 316L SS similar sheet material. The skeletal and lathy delta-ferrite-austenitic structures were observed in the fusion zone (FZ) due to non-equilibrium solidification, which is attributed to the different thermal cycle behaviour of the FZ. This morphology is explained by the pseudo phase diagram and the Schaeffler diagram of SS material. The tensile test showed that the microplasma arc welding process achieved a joining efficiency of 93%. The high cycle fatigue performance of welded specimens was analysed at different alternating stress amplitude. The presence of a dense delta ferrite phase in the austenitic matrix is responsible for fatigue failure of the welded specimen. However, the development of deformation-induced martensite in the crack initiation site promotes fatigue life. The crack initiation, propagation, and sudden failure site were investigated to explain the fatigue fracture behaviour.

Analysis of Fabricability of Flexible Waveguide Parts for Satellite Applications

Satellite onboard equipment includes waveguide transmission lines. One of the tasks to be solved is the temperature decoupling of the waveguide path and onboard equipment devices. In order to prevent waveguide path deformation during expansion/contraction due to thermal effects, the waveguide is equipped with a flexible waveguide section capable of changing the length without deteriorating radio technical characteristics. The paper considers the issues of fabrication of flexible waveguide parts, concerning the requirements for structure, properties, heat treatment of raw materials, dimensions of workpieces, equipment, and tooling. Within the study, we optimized and tested in practice operations of the technological process of extracting parts from sheet material, rolling, profiling, and shaping, which make it possible to manufacture parts of waveguide paths of the required quality.

Friction and Wear Behavior of Deep Drawing Tools Using Volatile Lubricants Injected Through Laser-Drilled Micro-Holes

In deep drawing processes, the use of lubricants is mandatory in order to prevent wear on tools and surface damage to the formed sheet metal components. Here, frequently used lubricants are synthetic and mineral oils, emulsions, and waxes. However, these conventional lubricants have to be applied to the sheet material prior to the forming operation and removed afterwards by cleaning processes. Additionally, the lubricants often contain substances that are harmful to the environment and to human health. To counteract these economic and ecological disadvantages, research is currently being conducted on a novel tribological system. For this, volatile media such as liquid carbon dioxide and gaseous nitrogen are being used, and are introduced directly into the friction zones between the tool and the sheet metal material during deep drawing under high pressure through special laser-drilled micro-holes. This paper covers the latest investigations and findings regarding the design of flow-optimized micro-holes, the laser drilling process, the friction characterization on tool radii, and the tool wear to be expected when using the lubrication medium CO2.

Parametric Effects of Single Point Incremental Forming on Hardness of AA1100 Aluminium Alloy Sheets

When using a unique tool with different controlled path strategies in the absence of a punch and die, the local plastic deformation of a sheet is called Single Point Incremental Forming (SPIF). The lack of available knowledge regarding SPIF parameters and their effects on components has made the industry reluctant to embrace this technology. To make SPIF a significant industrial application and to convince the industry to use this technology, it is important to study mechanical properties and effective parameters prior to and after the forming process. Moreover, in order to produce a SPIF component with sufficient quality without defects, optimal process parameters should be selected. In this context, this paper offers insight into the effects of the forming tool diameter, coolant type, tool speed, and feed rates on the hardness of AA1100 aluminium alloy sheet material. Based on the research parameters, different regression equations were generated to calculate hardness. As opposed to the experimental approach, regression equations enable researchers to estimate hardness values relatively quickly and in a practicable way. The Relative Importance (RI) of SPIF parameters for expected hardness, determined with the partitioning weight method of an Artificial Neural Network (ANN), is also presented in the study. The analysis of the test results showed that hardness noticeably increased when tool speed increased. An increase in feed rate also led to an increase in hardness. In addition, the effects of various greases and coolant oil were studied using the same feed rates; when coolant oil was used, hardness increased, and when grease was applied, hardness decreased.

The Method of Constructing a Multidimensional Model for Finding the Values of the Parameters of the Incremental Sheet Forming Process

The object of research is geometric models of the process of incremental forming of parts from sheet material. The subject of research is a graphical model for finding the optimal values of the parameters of the forming process based on multidimensional descriptive geometry. The author of the article discusses the main optimizing factors and process parameters. Particular attention was paid to the problems of constructing geometric models for determining the optimizing factors for incremental forming. The research method is a way of constructing a graphical optimization model of the process using the projection drawing of Radishchev for multidimensional space. Mathematical modeling was also applied to check the correctness of the obtained optimal parameters.

Design a multi-motion bed to help the Elderly people and sick

Most mishaps happening at clinical foundations treating older patients with portability hindrance are bedsores and slip-and-fall accidents. One reason for this high pace of mishaps is the absence of nursing faculty. So as to help parental figures in nursing old patients who are unable to move freely, we offer an arrangement and implementation of a wise bed in this work. This is the bed. Under the sheet material spread, a couple of weight sensors are passed to consider the two social orders' regular actual characteristics as well as the specific body portions where bedsores commonly arise. The body zone is divided into three vertical territories and three level zones to cope with the weight ulcer territory and prevent falls. Each microcontroller unit is in charge of monitoring pressure-differentiating data in one of the bodily regions separated on a level plane. In this review, a consistent weight distinguishing figure is offered that is useful for predicting the anticipated outcomes of bedsores and falling setbacks by taking into account both the strength and the length of weight of unambiguous body parts. Our preliminary findings reveal that a model magnificent bed serves a pair of human models of varied heights and burdens admirably.

A RESEARCH ON THE BREATHABILITY PROPERTY OF BABY DIAPER BACKSHEET

Disposable breathable diapers are considered as one of the most important developments in diaper sector. Breathable diapers keep the child’s skin dry and provide a comfortable feeling to the child. Breathability of diapers is obtained by using the breathable back sheet layer which is the most outer layer that the diaper comprises. In this study, the effects of laminating and printing processes on back sheet material breathability are studied. For this aim, four types of back sheet samples namely; film, printed film, laminated film and printedlaminated film are tested for breathability. For breathability testing, water vapour permeability test was applied with two different test devices which principally operate in different ambient conditions. As a result of the study, it is seen that, the breathability of back sheet component decreases as a result of printing and laminating processes. Also, it can be concluded that the ambient conditions for standard textile fabrics is not convenient for testing back sheet samples. Since, the test does not simulate the real ambient conditions of microclimate between the diaper and the child’s skin during diaper use.
