Stainless Steel 1.4571 - 316Ti

2011-12-8 · 316L, the low carbon version of 316 stainless steel, is immune to grain boundary carbide precipitation (sensitisation). This makes it suited to use in heavy gauge (over about 6mm) welded components. For elevated temperature appliions the high carbon variant, 316H stainless steel and the stabilised grade 316Ti stainless steel should be employed.

Comment on “steady state creep behaviour of silicon

The creep is shown, to be matrix lattice diffusion controlled. The difference between the apparent activation energy of creep and the activation enthalpy of matrix lattice diffusion is accounted for by the temperature dependence of both the shear modulus and, especially, the threshold stress.

The advantageous properties of CVI SiC/SiC composites such as their excellent high temperature strength, creep and corrosion resistances, low density, high toughness, resistance to shocks, fatigue and damage, and reliability make them ideal candidates for the replacement of metals and ceramics in many engineering appliions involving loads

Newtonian flow process in polycrystalline silicon …

Abstract. Some previous studies on hot-pressed and sintered SiC polycrystalline materials have been reexamined. Mechanical data and microstructures strongly suggest that the Newtonian creep behaviour observed in these SiC materials was induced by a disloion process operating in Harper-Dorn creep, rather than by diffusional creep as concluded before.

During 1921-1927, E.C.Bain made many important contributions to metallography by means of X-ray powder diffraction studies. He discovered the AuCu3 and Au3Cu superlattices, the face-centered structure of the Fe-Mn austenite, the Fe3W3C (or M6C) carbide in high-speed steels, and the Sigma phase in Cr-Ni stainless steels.

2011-11-22 · Silicon carbide grain boundaries films are an exemplar for amorphous films that are reported to crystallize upon heat treatment (e.g., as reported in the Al-doped case [32,33]). The modeling of oxycarbide glass films could be similar to that described for oxynitride films and involves some of the same investigators in an extant DOE program on SiC.
