THE OXIDATION RESISTANCE OF HIGH ALUMINUM HEAT RESISTANT STEELS
Abstract: In this research, the oxidation behaviour of high Aluminum heat resistant steel (%25Cr,%20Ni,%8Al) hasbeen evaluated at the temperature range of (1000-1300ºC).The results showed that there was no countinous healinglayer on the surface of the alloy when Al increased up to %5.5 and the oxidation resistance of steel decreased due toformation of spinel oxides on the surface.By increasing ...
متن کاملCavitation During Superplastic Forming
Cavitation is the opening of pores during superplastic forming, typically at grain boundary triple points or on second phase grain boundary particles during slip of grain boundaries. Theories for the initiation of cavitation are reviewed. It seems that cavitation is unlikely to occur by processes intrinsic to metals such as dislocation mechanisms or point defect condensation. It is proposed tha...
متن کاملOptimization of Superplastic Forming Technology
The objective of this paper is a superplastic forming (SPF) technologies design and optimization. The conditions of superplasticity are very sensitive to strain rates and temperature characteristic of deformation process. The presented work gives an approach to design the SPF technologies that satisfies such conditions.A possibility to decrease the temperature of the industrial forming of the T...
متن کاملBest practice in heat treatment of large dies made of hot work tool steels
Tool steels are a widely used material for construction of tools designated for shaping and forming of metal, plastic and other elements in mass production. These elements include extruding dies, pressure casting dies, moulds, punches and various other elements for plastic shaping of other materials preheated to temperatures in the range of 250-700 °C (Fig. 1). Since shape stability constitutes...
متن کاملThe Superplastic Forming of Bulk Metallic Glasses
Superplastic forming (SPF) is introduced in this article as a net-shape processing method for bulk metallic glasses (BMGs), commercially known as Liquidmetal® alloys. This method decouples fast cooling and forming of the BMG. Forming takes place in the supercooled liquid region, where the BMG exists as a highly viscous liquid and increases its fl uidity with increasing temperature. The SPF meth...
