Characteristic Points of Stress-Strain Curve at High Temperature
Determination of critical points on hot stress-strain curve of metals is crucial in thermo-mechanical processes design. In this investigation a mathematical modeling is given to illustrate the behavior of metal during hot deformation processes such as hot rolling. The critical strain for the onset of dynamic recrystallization has been obtained as a function of strain at the maximum stress. In a...
متن کاملA Study on the "Impatience" Characteristic of Human
From Quran’s perspective, the universe and human system has been interpreted as “the best”. However, in Quranic teachings we are encountered with some concepts such as human “impatience”. Impatience means to be greedy and anxious. “Impatience” is the fact that human shows restlessness when he becomes poor, and when being in a state of wealth, he denies it from others. Regarding blaming or prais...

متن کاملMICROSTRUCTURE CHARACTERISTIC OF ALUMINUM TITANATE SYNTHESIED BY BOTH SOLID- STATE AND SOL-GEL PROCESSES
A comparing study on formation and microstructure features of aluminum titanate is investigated through both solid-state and sol-gel processes. Aluminum titanate formed by firing at 1350ºC and 1450ºC for 4h in solid-state process. In the sol-gel process formation of submicron sized particles is followed by addition of sucrose into the transparent sol. XRD analysis was confirmed the formation of...
متن کاملCharacteristic dimensions for heat transfer
Taking into account the actual need and importance of introducing the main concepts of heat transfer in the curriculum of science and engineering studies, and starting from the solutions of the non-stationary heat conduction equation, we discuss the length and time scales involved in the laws of this phenomenon and the limits of validity of its current description, hoping that these concepts ca...
