Abstract PRODEC STAINLESS TYPE 316 is a standardized grade in plate and bar with an improved machining capability over the conventional AISI Type 316. It is a product of extensive laboratory testing and application proven. Its improved machinability offers: shorter machining time; longer tool life; better surface finish; less distortion problems; more homogeneity in microstructures; and marginally increased resistance to corrosion. This datasheet provides information on composition and physical properties. It also includes information on machining. Filing Code: SS-549. Producer or source: Avesta Sheffield Inc.

Mechanical And Physical Properties

Carbon compounds have high dielectric losses, which means that these materials are heated efficiently by microwave irradiation. Carbon materials can be used as microwave absorbers in polymeric materials that are transparent to microwave irradiation. In this paper, carbon-reinforced polypropylene composites were exposed to microwave irradiation and then their dynamic mechanical thermal properties, electromagnetic shielding, and surface morphology were investigated. The test results showed that mechanical and physical properties of carbon–polypropylene composites improved following microwave exposure. The dynamic mechanical thermal analysis results showed that their storage and loss modulus were improved following microwave treatment. It is postulated that microwave irradiation heats carbon materials, which is likely to melt neighboring matrix thus improving interfacial adhesion and structural defects.

Insight Into

The paper examines the behaviour of a highway embankment in an area of discontinuous permafrost about 18 km northwest of Thompson, Manitoba. Frequent maintenance has been required. Research involved site investigation, laboratory testing, installing instruments, data collection, and numerical modeling. The paper reports data from almost 3 years of observation. Measurements of ground temperatures suggest that formerly ice-rich foundation soil has thawed under the toe and side-slope. Approximate values of segregation potential have been back-calculated from observations of settlements and temperatures. Results provide insight into the nature and cause of deformations of the embankment.
