(30 lb) of P/M parts with an increase expected in the next several years (Fig. 1). A slightly lower amount is used in Japanese automobiles (Table 2) (Ref 6), but automotive application of P/M parts is still the dominant use in Japan as well (Fig. 2). The growth of P/M parts in automobiles is due to[r]

During the anodic etch, a high acid content, low solution temperature, and high current density will minimize smut formation. Carryover of water into the anodic etching solution should be held to a minimum, and long transfer times after the anodic etch should be avoided. Cold rolled steel that has b[r]

approximating actual response through the model of the behavior. For materials that do not have a fatigue limit, or for finite-life estimates of materials that do, the fatigue strength at a given number of cycles can be substituted for the intercept on the stress-amplitude axis. Examples of the Haig[r]

Therefore, at the same temperature, the cooling rate at the centerline is greater than the cooling rate at the location a distance y from the centerline. In addition, the cooling rate of the heat-affected zone is less than the cooling rate in the weld pool at the same temperature. Example 4:[r]

(Eq 12) (Eq 13) For this system, the optimum allocation beyond the first stage of sampling is the same for fixed total cost as for fixed total variance. Example 1. In sampling a trainload of metal pipe for the percentage of an alloying element, the standard deviation is 0.25 between cars, 0.15 wit[r]

before the stress reversal and transformation of the core occurs well after the stress reversal. The surface transformation helps to push the surface stress rapidly into compression, and compression yielding occurs. Before the core transformation, the core deforms plastically.
