Mechanical Properties And Corrosion

High temperature sintering, i.e. at temperatures above 1150°C is a well-known concept in industry. For example in the metal injection molding (MIM) process sintering temperatures employed are higher than 1250°C for ferrous alloys [1]. The advantages of this technology respect to conventional sintering are many: an increase in the homogeneity and in density, a better pores morphology, the elimination of some reducible oxides. All these lead to better mechanical properties and corrosion resistance which means better performance [2, 3, 4, 5].

Inconel 713C

Inconel 713C alloy was tried to manufacture by using MIM(Metal Injection Molding) process. The high-temperature mechanical properties of MIMed Inconel 713C were also investigated. Processing defects such as pores and binders could be observed near the surface. Tensile tests were conducted from room temperature to 900°C. The result of tensile tests showed that this alloy had similar or somewhat higher strengths (YS: 734 MPa, UTS: 968 MPa, elongation: 7.16 % at room temperature) from RT to 700°C than those of conventional Inconel 713C alloys. Above 800°C, however, ultimate tensile strength decreased rapidly with increasing temperature (lower than casted Inconel 713C). Based on the observation of fractography, initial crack was found to have started near the surface defects and propagated rapidly. The superior mechanical properties of MIMed Inconel 713C could be obtained by optimizing the MIM process parameters.

Cr Content

In recent years, metal injection molding (MIM) has been adopted as a process for manufacturing a solenoid valve which is a component of an electronic fuel injector, and PB permalloy components have been commercialized. However, Ni, an element of PB permalloy, is expensive material, making it difficult to produce the fuel injector component at a low cost. As a solution to this problem, we studied the magnetic and mechanical properties of Fe-Cr-Si alloys by MIM process. These results revealed that the magnetic and mechanical properties were improved by reducing Cr content. However, reducing Cr content is expected to reduce corrosion resistance of the alloys. In this study, Fe-Cr-Si-Mo alloy specimens containing Mo to improve corrosion resistance are manufactured by MIM process, and we investigated the magnetic and mechanical properties. These results revealed that Fe-10Cr-3Si-2Mo alloy is a material with an excellent balance between magnetic and mechanical properties.
