The effects of isothermal aging at temperatures between 550-850 ?C for durations of 1-100 h on microstructure, tensile properties, and impact fracture behavior of 316L austenitic stainless steel weld metal have been ...

In all engineering applications where solid surfaces slide on each other, friction plays an important role. It becomes even more important, particularly in metal forming processes where the two sliding materials are metallic. ...

In deep mixing method lime or cement and or a combination of the two are mixed with in-situ soils by means of an auger to improve the strength properties of the soils. Strength of the improved soils may be evaluated in ...

Wire-brushing is used for different purposes such as removing metal surfaces oxides, increasing surface brightness, improving fatigue properties and surface activation before coating. The wire-brushing severely scratches ...

Equi-atomic Nickel-Titanium (NiTi or Nitinol) has the ability to return to a former shape when subjected to an appropriate thermo-mechanical regime. Pseudoelastic and shape memory effects are some of the behaviors presented ...

Numerous parameters influence bit selection process, which considering all them is not normally feasible. Existing methods use limited number of these parameters to choose a suitable bit for a specific drilling condition. ...

Gotvand dam is a rock fill dam located in Khoozestan province in Iran on Karun River. It will be constructed on weak mudstone and layers of sandstone. These layers are intermittent of medium strength with uniaxial compressive ...
