Strong support for the theory of hot cracking was provided by varestraint welding tests of the casualty steel plate to determine the weld hot-cracking susceptibility of the steel. The great number of cracks that formed...

... [ 12 ], the mechanical behavior of the steel must show a strain hardening coefficient n (as measured by a tension test with the ASTM standard) higher than 0.1 in its hot rolling raw state. If this is achieved, the steel can be used for cold work operations such as bending, stretching, and drawing...

The heads of most fasteners are formed by hot or cold forging, depending on the type of material and size of the bolt. In addition to being a relatively low-cost manufacturing method, forging...

For the same reason, those tests for measuring fracture toughness that rely on fractography may not work well with high-toughness ceramics. Uniaxial Tension Failure in pure uniaxial tension is rare in ceramics, except in carefully designed...

The stress conditions in this test (from 47,000 tension to 47,000 compression) were so different from service stressing (from zero to 62,500 psi. tension) that a Haigh machine was used for fluctuating axial loads. At the quoted service loadings the test pieces broke...

When this occurred, the root of the weld would have been under tension, which would create an ideal site for a crack to initiate. Cracks 1 and 2 probably originated during hydrostatic tests of the heater or shortly...
