Comparison between autogenous welding and with addition of nickel on nd:yag pulsed laser welded UNS s32750 duplex stainless steel
(2019-01-01)
Duplex stainless steels (DSS) have a biphasic microstructure with equal proportions of austenite and ferrite, which gives them excellent mechanical strength and corrosion resistance compared to austenitic stainless steels. ...
Fatigue Strength of X45CrSi93 stainless steel applied as internal combustion engine valves
(Elsevier B.V., 2011-01-01)
Stainless steels are used to intake and exhaust valves production applied as internal combustion engines. In general valves are requested to support cyclic stresses applied due to opening and closing processes during the ...
