Steel precipitation hardening
網頁NiAl-strengthened high-strength steels usually have high Ni and Al contents in order to form hardening particles. Here, several new low-Ni steels are reported, which achieve a combination of relatively low cost, high strength and good ductility mainly through the precipitation of high number densities of nanoscale NiAl precipitates as characterized by … 網頁2024年1月28日 · Precipitation hardening is a heat treatment process that is used to improve the corrosion resistance of metals. Age hardening is typically used on aluminum alloys, while precipitation hardening is typically used on stainless steel alloys. Age hardening involves heating the metal above its critical temperature and then allowing it …
