Evaluation of tensile strength of dissimilar metal pure aluminium and pure copper friction weldsSeveral industrial applications demand the dissimilar metal joints of aluminium and copper, and dissimilar metal welding has been always a challenge. An attempt has been made in the present work in joining ...

Magnesium matrix composites reinforced with SiO2 coated carbon fibers have been investigated, with an emphasis given on the relation between the material strength and interfacial microstructure. The composites were studied as a function of aluminium (Al) content that is varied between 0 and 9 wt%. ...
Concrete is a brittle material, so its compressive strength is high, buttensileis low. 混凝土是一种脆性材料, 抗压强度高, 而抗拉强度则较低. 期刊摘选 The condition of uniaxial stress is approximated in prismatic bars subjected to pure axialtensile. ...
Due to this bending, the calculated shear stress is not the pure shear stress but a shear stress component where other stress components are considerably smaller. Hence, the shear test too does not provide results that can be directly compared with the inherent strength of the material. In the...
A new pattern of heat treatment is produced known as retrogression and reaging (RRA) heat treatment to increase strength and hardness of aluminium alloy 7075 due to the need of high strength in application such as in aerospace industry. ... SM Nazizi 被引量: 0发表: 2009年 加载更多来源...
EFFECT OF WELDING PARAMETERS ON THE MECHANICAL PROPERTIES OF FRICTION STIR WELDED DISSIMILAR ALUMINIUM ALLOYS 6101 & 6082 The main objective of this research work was to study and optimize the effect of various welding parameters on the mechanical properties i.e. Tensile Strength and Impact Strength...
The study was made on pure commercial alloy to minimize the effect of alloying element. We have found that the higher the cold work, the steeper and sooner the decline in yield strength is. The response of metal to temperature does not follow a linear trend with the amount of cold work ...
