| Abstract: | The solid solution strengthening effect and mechanism of alloying elements on platinum were discussed.The mechanical properties of platinum group metals and Pt-Rh,Pt-Ir and Pt-Pd-Rh alloys were introduced.A small quantity additions of Ir,Ru,Mo,Au etc can be used in Pt-Rh and Pt-Pd-Rh alloys with higher Rh or Pd content,and the trace additions of Zr,Hf and rare-earths can be used in the alloys with lower Rh or Pd content,to improve and increase the mechanical properties at high temperature with different str... |
