Carbide Structure and Fracture Toughness of High Speed Tool Steels
In the present study, M2 high speed steels were fabricated by using electro-slag rapid remelting process. Carbide structure was analysed and the fracture toughness and hardness were also measured after austenitization treatment at 1190 and 1210C followed by tempering treatment at 535C for billets with various diameters from 16 to 60 mm. Electro-slag rapid remelting (ESRR) process is an advanced...
متن کاملMicrostructure and Fracture Toughness of Hot-Pressed Silicon Carbide Reinforced with Silicon Carbide Whisker
The effects of p-Sic whisker addition on the microstructural evolution and fracture toughness (K,c) of hot-pressed SIC were investigated. Most of the whiskers added disappeared during the densification process by transformation into the a-phase. The remaining whiskers acted as nuclei for grain growth, resulting in the formation of large tabular grains around the whiskers. The tabular grains aro...
متن کاملDisorder in Rare Earth Metal Halide Carbide Nitrides
Structural frustration in a rod packing exhibits analogy to frustration effects in antiferromagnetic systems. Like the spins in a triangular Ising net, rods with periodic contour may arrange randomly. Such frustration effects are observed in rare earth metal carbide nitride halides composed of C2 centered RE6 octahedra and N centered RE4 tetrahedra. These can be connected in varying sequences t...
متن کاملOn Measurement and Interpretation of Toughness Behaviour of Carbide Tools
The actual significance of any definition of toughness behaviour of carbide tools depends on the existence of an interrelation between the auality as defined and the occurrence of chiuninn and uremature failure in cuttin?. V'hile at ?resent there is no ademate analvsis available and the existing classifications do not even nrovide a ?ualitatiVc. indication for tool choice, one first has to eval...
متن کاملImproving NASICON Sinterability through Crystallization under High-Frequency Electrical Fields
The effect of high-frequency (HF) electric fields on the crystallization and sintering rates of a lithium aluminum germanium phosphate (LAGP) ion conducting ceramic was investigated. LAGP with the nominal composition Li1.5Al0.5Ge1.5(PO4)3 was crystallized and sintered, both conventionally and under effect of electrical field. Electrical field application, of 300 V/cm at 1 MHz, produced up to a ...
