The Effect of Material Properties on Tension Zone and Boundary Shear-Stress in Extrusiontric extrusion process of extrusion ratio 4 and a half cone angle of 45°. The extrusion speed was 0.1/min for aluminum and.003 in/min for superplastic Pb-Sn. The stress components along and perpendicular to the flow lines were calculated for different values of workhardening and strain-rate exponent作者: 財(cái)產(chǎn) 時(shí)間: 2025-3-22 08:27 作者: 放氣 時(shí)間: 2025-3-22 09:14
The Extrusion of Rate Sensitive Materialsmphasis is given to the importance of determining the area profile of the die, and through it the strain rate profile. Four different definitions of the mean strain rate are considered, and it is shown that the root mean power strain rate is the appropriate one to use for working load calculations. 作者: 嫌惡 時(shí)間: 2025-3-22 14:35 作者: inscribe 時(shí)間: 2025-3-22 19:28
The Effect of Homogeneity on the Formability of 7000 Series Aluminum Alloys for Cartridge Casesieved; the main problem appears to be burn throughs which infrequently occur in the side wall of the cases. The nature of the failure is such that (i) severe damage occurs to the weapon upon burn-through and (ii) failure analysis is difficult. The general interpretation is that small tears occur dur作者: DAFT 時(shí)間: 2025-3-22 22:57
Effect of Plastic Anisotropy on Drawing Characteristics of Aluminum Alloy Sheet good drawability, a fine grain size, and minimum earing tendencies. The latter property is one manifestation of anisotropy for which control is attempted by means of fabricating practices designed to balance annealing and rolling crystallographic textures.作者: Harridan 時(shí)間: 2025-3-23 04:22
Analyses of Deformation and Texture as Functions of Fabrication in Mandrel-Drawn Tubing00 MWe boiling water reactor requires almost 500,000 ft of nominally l/2-in.-diam Zircaloy tubing per core loading. The production of such tubing is potentially a very large-scale operation with the advent of increasing numbers of power reactors.

The Validity of Simulating Tests in Evaluating Lubricants for Deformation Processesnty attached to the magnitude of interface friction. Even the simplest theory must account for the effects of friction on forces, power requirements and material flow, and the magnitude of this friction must be known-together with the correct value of the flow stress-if the validity of a theory is t作者: 售穴 時(shí)間: 2025-3-24 00:34 作者: CHANT 時(shí)間: 2025-3-24 06:06
