The shape memory effect exhibited by Fe-Mn-Si based alloys is due to the y(f.c.c.)-e(h.c.p.) martensitic transformation. The martensitic transformation induced by traction at room temperature in a Fe16Mn-9Cr-5Si-4Ni (%mass) is here studied by optical microscopy, scanning electron microscopy, transmission electron microscopy and scanning tunnelling microscopy. The martensitic microstructure and ...

Z. Naturforsch. 38b, 1069-1071 (1983); received May 13, 1983 Pseudohalogens, IR Spectra, Nickel The title compound reacts with cyanogen halides, XCN (X = Br or I) to give the complexes L2(X)(CN)Ni (L = P(OPh)3, X = Br or I). The oxidative addition of (SCN)2 and (SeCN)2 to the same compound results in the formation of L2Ni(XCN)2 (X = S or Se). All the complexes have been characterized by element...

Abstract The application of aluminum alloys at elevated temperatures has been attractive for decades, and Al-Ni-based have recently recognized as potential candidates. effect Mn on Al-4Ni alloy investigated in this work. Addition transformed the eutectics from Al 3 Ni/α-Al to 9 (Ni,Mn) 2 /α-Al phases. also improved tensile strength both 25°C 250°C. yield increased 48 MPa 92 with 1.87% then 117 ...
