NiTi alloys with equiatomic composition of NiTi have the highest technological interest for its potencial application in differents areas such as biomedical, naval, aerospace, nuclear, automobilist , robotic,etc. In this work , it was used a 50Ni50Ti at % powder mixture, comercially pure, prepared by mechanical alloying in a Attritor with the following conditions: the milling speed and the...... hiện toàn bộ
Failure Pressure Estimations for Corroded Pipelines
Materials Science Forum - Tập 758 - Trang 65-76
Matherson L. da Silva, H.S. da Costa Mattos
The goal of the present paper is to propose a simple methodology to estimate the failure pressure of thin-walled metallic pipelines with arbitrary localized corrosion damage. This methodology is conceived as a preliminary tool for a quick analysis of the structural integrity of real corroded pipelines. Due to the different possible geometries of the corroded region, the exact analysis of t...... hiện toàn bộ

The Influence of Aluminium Alloy Quench Sensitivity on the Magnitude of Heat Treatment Induced Residual Stress
Materials Science Forum - Tập 524-525 - Trang 305-310
J. S. Robinson, David A. Tanner
To produce useful strengthening, precipitation hardenable aluminium alloys rely on rapid quenching from the solution heat treatment temperature to suppress the formation of coarse equilibrium second phases. An unavoidable consequence of the rapid quenching of thick sections is the severe thermal gradients that quickly develop in the material. The attendant inhomogeneous plastic flow can th...... hiện toàn bộ
Mechanisms Influencing the Formation of the Carbonized Layer Relief on the Polymer Surface after the Ion-Plasma Treatment Modeling
Materials Science Forum - Tập 938 - Trang 148-155
Anton Y. Beliaev, А. Л. Свистков
The work is devoted to the discussion of hypotheses that are put forward to explain the processes occurring during ion-plasma treatment of polyurethane. A carbonized layer forms on the surface of the polymer as a result of ion-plasma treatment. However this layer is not even. Wavy relief, the geometric features of which depend on the fluence (the number of ions entering the unit surface of...... hiện toàn bộ

Characterization and Mechanism Analysis of Growth Bands in Chemical Vapor Deposited ZnS
Materials Science Forum - Tập 944 - Trang 631-636
Peng Fei Zhang, Hongwei Li, Hai Yang, Nai Guang Wei, Jian Ming Li, Dongxu Li
In the chemical vapor deposited zinc sulfide, it often appears obvious light and dark growth bands along the growth direction, which will affect the homogeneity of optical properties of CVD ZnS and the efficiency of subsequent heat treatment. X-ray diffraction, Metallographic microscope and SEM were used to detect the crystal structure, grain size and microstructure, and the concentration ...... hiện toàn bộ
