Book Description
This report presents the results of a state-of-the-art survey covering tantalum and seven of its alloys. All data are given in tabular and graphical form covering some of the more important physical, mechanical, and metallurgical properties for each material. References are given at the conclusion of each material section.

Book Description
Tensile tests were made on specimens of commercial Ta of different grain-sizes, and the variation of lower yield stress with grain-size 2d was used to assess the effect of temperature (23, -78 and -196 deg C) and strain-rate (0.0019 and 0.0996 sec. at each temperature) on the parameters sigma sub i and k sub y in a Petch type equation. The results indicate that the sensitivity of the yield strength to temperature and strain-rate arises almost entirely from the effects that these variables produce on sigma sub i. The high resistance of Ta to brittleness has been confirmed, all of the specimens showing pronounced necking and predominantly fibrous fractures; on the fracture surfaces of the coarser grained specimens tested at -196 deg C (both strain rates) some cleavage facets were observed. The greater ductility of Ta relative to Nb, Mo, and mild steel is attributed to a low value of k sub y and a high value of shear modulus.

Book Description
A study was made of the effect that tempering temperature has on plastic properties and specific strength for composite specimens made of Al and its alloys with steel fiber, prepared by welding, explosion, and subsequent cold drawing. It is shown that the strength of the reinforced material rises somewhat after heatings at 100-150C compared with the strength obtained after welding and rolling. Heating of reinforced material at more elevated temperatures (200C and higher) leads to a reduction in its strength owing to softening of the maxtrix metal and fibers.
