MICROSTRUCTURE AND MECHANICAL PROPERTIES OF ULTRAFINE-GRAINED IF STEEL SHEETS PRODUCED BY CONSTRAINED GROOVE PRESSING

If the number of cycles-to-failure was below 1.10 7 , the fracture surfaces of AZ 91HP specimens fatigued in ambient air and saltwater spray were similar. Fatigue cracks emanated from voids in both cases, and the fracture surfaces showed transgranular crack propagation[r]

Several types of adhesion tests have been devised, for example, the “Scotch tape” test, the scratch test,
the linear peel test, and the inflated membrane test (Valli, 1986; Mittal, 1978). The latter test has been
performed on micromachined structures (Senturia et al., 1987), but[r]

a problem can be formed into dimensionless parameters, the number of parameters being less than the number of variables. This is a great advantage, because fewer experimental runs are then required to establish a relationship between the param- eter than between[r]

In addition to flaking, blisters can be produced by excess hydrogen (Fig. 81). Hydrogen can also be introduced into steels during other processes, such as welding, pickling, bluing, enameling, or electroplating. Consequently, it is necessary to bake the material after such processes[r]

Many surgical techniques have been described for the management of neglected Achilles ruptures. The primary goal of any surgical treatment is to restore the function and strength of the gastrocnemius-soleus complex by recreating the optima[r]

Molecular Mechanism of Polymer - W a l l Friction:

Die Casting. Manually operated casting machines were patented as early as 1849 (Sturgiss) and 1852 (Barr) in an effort to satisfy the insatiable demands of a growing reading public by way of rapidly cast lead type. These early inventions led to Ottmar Mergenthaler's Li[r]
