The thermally induced fcc → dhcp martensitic phase transformation was investigated in two different CoFe alloys (Co-5.75 and 6.0at.% Fe). Analysis by transmission electron microscopy methods yields that in both alloys the transformation proceeds by

Periodic contrast modulations were observed by high-resolution transmission electron microscopy (HRTEM) methods at the transformation interfaces between different close packed structures in CoFe alloys. Image simulations show that moire fringe patter

The thermally induced fcc↔dhcp martensitic phase transformations were studied in a Co-5.75 at.% Fe single crystal. Transmission electron microscopy (TEM) methods were applied including in-situ experiments; lattice fringe and high-resolution transmi

The dissociation of the superlattice dislocations in Ni3(Al, Ta) has been studied by transmission electron microscopy (TEM) weak-beam methods. Single-crystal specimens were deformed at liquid-nitrogen temperature, at room temperature and at 270°C, a

The thermically induced h.c.p. to f.c.c. martensitic phase transformation was studied in Co-32 at.% Ni single crystals by the weak-beam method of transmission electron microscopy (TEM). In this alloy the mean transformation temperature is at RT and t

The intermetallic alloy Ni3Al has the ordered Ll2 structure, which is based on the fcc lattice (Fig. 1). Ni3Al shows an anomalous behaviour of both critical resolved shear stress (CRSS) and work-hardening rate with temperature. Since the magnitude of

Al alloys containing Mg and Si are used in an increasing number of technical applications. These alloys have a high specific strength (yield strength / density) that is caused by the formation of small precipitates (Guinier-Preston zones GPZ). There

Defect recovery andlong-range ordering(LRO) in Ni76Al24+0.19at.%B (400 wt.ppm) were studied by means of residual resistometry, TEM methods and microhardness testing. The material was cold-rolled with intermediate annealings and the samples were prepa
