The microstructure of forged products significantly impacts their properties, and defects or carbide distribution are not visible to the naked eye. Isothermal compression tests on M50 steel with a Gleeble 3500 tester were conducted study behavior during forging. Tests examined hot deformation within temperature range 900–1200 °C strain rate 0.01–10 s?1. Power dissipation efficiency (?) flow ins...
This research introduces an advanced forging method to produce the door frame of the wind turbine tower. The advantage of the new forging method is the increase of raw material utilization ratio and the energy saving. In the conventional method, the door frame is hot forged with a hydraulic press and machined out lots of material because of the big difference between forging shape and final mac...
In warm and hot forging, the dies are subjected to high contact pressures and temperatures. The selection of the die material, hardness and coating is critical for increasing die life. Recent studies indicate that ceramic dies and various surface treatment techniques represent, in certain applications, cost effective techniques for improving die life. This paper reviews the state of technology ...
The purpose of this research is to analyze the forging of bevel gears based on conventional forging method with material number 1.7131 with finite element method by means of SUPER FORGE software and to compare it with experimental cold orbital forging results.After doing simulation of conventional forging and obtaining press tonnage due to orbital forging method with DEFORM software, orbital fo...
This paper presents a comparative study of Continuous Stirred Tank Reactor concentration control using Particle Swam Optimization and Bacterial Forging Optimization. Continuous stirred tank reactor plays a very important role in process industry. This paper presents the optimal design of PID controller based on Particle Swarm Optimization and Bacterial Forging Optimization. The first step is th...
The present study was carried out to investigate the effect of alloying elements and thermo-mechanical treatment (TMT) i.e. hot rolling and forging with different reduction ratios on the hardness (HV) and impact toughness (J) of heat-treated low alloy steels. An understanding of the combined effect of TMT and alloying elements and by measuring hardness, impact toughness, resulting from differen...
Aluminium is totally recyclable with no downgrading of its qualities, but in the process of typical conventional aluminium recycling, there are quite a number of negative impacts. The recycling of aluminium and its alloys by direct recycling method is relatively simple, consumes small amount of energy, produce small amount of waste and does not have a harmful effect on the environment. This app...
AZ31 magnesium alloy is considered as a promising alloy in various applications and industries. Furthermore, to design a proper hot working process (rolling, forging and extrusion), the assessment of hot working behaviour of the alloy is necessary. Accordingly, the hot deformation behaviour of AZ31 alloy was studied through hot compression testing method This was carried out in a wide range of ...
