Thickness reduction, e T and the elongation of Ni-Pd-P metallic glass up to 40 and 26 per cent can be attained in rolling. Deformation bands develop and are wavy in appearance and similar to single crystals of pure b.c.c. metals. Observations at vari

Recent excavations of the Bronze Age site of Sarazm (35W2000 B.C., uncalibrated) were undertaken by a collaborative team of archaeologists from the U.S.S.R. and U.S.A. The site is located in the Zeraoshan Valley in Tadjikistan SSR. A series of radioc

The crystallization of Ni55Pd35P10 alloys was examined by isochronal resistivity and hardness measurements, along with observations of the phase transformation in the heating stage of a transmission electron microscope (TEM). The resistivity temperat

Deformation and fracture of a Ni55Pd35P10 metallic glass have been examined in a tensile stage in a transmission electron microscope. It is observed that a plastic zone appears at the crack tip in advance of crack propagation. The microscopic fractur

Deformation and fracture of partially crystallized Ni55Pd35P10 amorphous alloys have been investigated. The samples with a few percent crystallization show a fracture stress (175 kg mm−2) and apparent Young's modulus (19.5×103kg mm−2) greater th

Mechanical behaviour, deformation and fracture have been investigated for amorphous Ni-Pd-P alloys made by an improved Pond and Maddin method. The stress-strain curves of Ni55Pd35P10 and Ni63Pd17P20 show quasi-brittle behaviour with average fracture

Summary A large increase in the critical shear stress of high-purity aluminium single crystals can be achieved by water quenching, instead of furnace cooling, after annealing at a high temperature. This quench-hardening effect is insensitive to purit
