Investigations into the mechanical strength anisotropy of Sorbitol Instant compacts made by uniaxial compression Article in Advanced Powder Technology 18(4) .   The indirect tensile test was applied for the determination of the green strength of the powder compacts, and test results were compared to that of a more conventional 3-point bending test. The substantial dependence of green strength on both the amount of impurity element in the core of the powder particles and the compaction pressure is Cited by: 4. powder compacts, and known as green strength, has been traditionally determined by means of a three points bending test (MPI Standard 15 - 51); but, it is rarely used. The c and φ values are first adjusted for anisotropy before they are used in the shear strength computation. For more information on this strength model, refer to the chapter in the SLOPE/W engineering book on material strength. The input parameters defined for the anisotropic strength of soil #1 are as shown in Table Size: 66KB.

Towards an Improved Understanding of Strength and Anisotropy of Cold Compacted Powder A Thesis Typical force displacement curve during tensile reloading, (b) Calculated strength Towards an Improved Understanding of Strength and Anisotropy.   The mechanical characteristics (σt, τ) of powder metallurgy steels depend upon the porosity as a weakening factor and work hardening as a strengthening one. The tensile strength is more sensitive to porosity and less susceptible to work hardening than the shear strength. The compressive yield strength depends practically only upon work hardening and Author: Yu. G. Dorofeev, G. A. Dreev. @article{osti_, title = {Mechanical properties of a titanium blading alloy.

Compared with the large powder, the tensile strength, yield strength, and elongation of the compact with the small powder were improved by 14%, %, and %, respectively. This paper studied the effects of powder size on densification, microstructure, and mechanical properties of the hot isostatic-pressed 2A12 aluminum alloy powder : Xina Huang, Lihui Lang, Gang Wang, Sergei Alexandrov, Sergei Alexandrov.

Powder Compacts Although early examples can date back to the s, compacts started to become widely used in the mid s. Their popularity peaked from the s to around the late 60s at which time disposables with refill blocks began to take over as more convenient. Tensile Tester for Quality Control and Research Tensile strength is a fundamental, primary property of powder as it represents the inherent particle to particle attractive forces that develop when a mass of particles is compacted. The value provides a terminal point of the yield loci of failure for samples in given states of compaction. You searched for: powder compact!
