In this study, high-carbon, chromium alloy steel (100Cr6) having the initial spheroidized microstructure was welded using the rotary friction welding method. The effects of process parameters such as friction time and friction force were experimentally investigated. The friction welded joints were produced of two 100Cr6 steel rods. In order to examine the microstructure and mechanical properti...
In this study, friction stir butt welding of Mg and Al alloys with applying Zn interlayer was performed. To obtain optimum condition, a combination of two travel and three rotation speeds were selected. Mg-Zn and Mg-Al-Zn IMCs, Al solid solution and residual Zn, were the most common phases in the stirred zone, which eliminated the formation of Al-Mg intermetallics. The maximum mechanical proper...
the purpose of this article is to present a thorough picture of liquidity managment. the first section of the article disusses the internal and external factors affecting the liquidity conditions of corporations. in the next section the effects of company size, industry type, production cycle and the efficiency of management on the liquidity needs are discussed. in the final section the relatio...
Background: One of the most important factors in the proper functioning of the military is the accurate assessment of feedback. Among these, the proper knee joint Proprioception is one of the most important factors in this regard. This study was performed to Evaluation of knee joint Proprioception Changes in military forces following a period of a static and dynamic stretching of hamstrings, qu...
Reform Prolog is an (dependent) AND-parallel system based on recursion-parallelism and Reform compilation. The system supports selective, user-declared, parallelization of binding-deterministic Prolog programs (nondeter-minism local to each parallel process is allowed). The implementation extends a convential Prolog machine with support for data sharing and process managment. Extensive global d...
Numerical probabilistic analysis for slope stability in fractured rock masses using DFN-DEM approach
Due to existence of uncertainties in input geometrical properties of fractures, there is not any unique solution for assessing the stability of slopes in jointed rock masses. Therefore, the necessity of applying probabilistic analysis in these cases is inevitable. In this study a probabilistic analysis procedure together with relevant algorithms are developed using Discrete Fracture Network-Dis...

To obtain optimum condition, a combination of two travel and three rotation speeds were selected. Mg-Zn and Mg-Al-Zn IMCs, Al solid solution and residual Zn, were the most common phases in the stirred zone, which eliminated the formation of Al-Mg intermetallics. The maximum mechanical proper...
The fine grain structure of friction-stir welded aluminum alloys is unstable during post weld heat treatment and some grains abnormally grown. In this study, the sequence of abnormal grain growth during T6 heat treatment of Al-7075 friction-stir weld and its effect on mechanical properties of the weld was studied. The results showed that heat treatment in 510 ˚C resulted in drastic grain growth...
The influence of heat-input and pre-heat treatment on the structure, mechanical and corrosion behaviors of 2205 duplex stainless steel joint by means of GMAW process was the goal of this study. In this regards, the welding process was done using different heat input in the range of 0.6 to 1.4 kJ/mm and different pre-heating treatments in the range of 25 to 100 oC. The microstructural properties...
