Factors Affecting the Inherent Hardenability of Steel predictions and a pearlite growth model based on site saturation at grain corners leads to a good prediction of the hardenability of steel. Hardenability (multiplying) factors for carbon, manganese, silicon, chromium, nickel, and molybdenum have been developed for hypereutectoid low-alloy steels in.

TTT diagram indicates a specific transformation starts and ends and it also shows what percentage of transformation of austenite at a particular temperature is Size: KB.

Factors affecting hardenability. Any factor that moves the nose of the TTT curve to longer times will increase the hardenability of the steel. The important factors are (i) carbon content, (ii) austenite grain size and (iii) alloy composition. The hardenability increases with increasing carbon content and generally the hardenability.

So the incubation period for the austenite to pearlite increases i.e. the C curve. The initial austenite grain size of boron microalloyed steel with three different amounts of boron (20, 40, and 60 ppm) was investigated under different heating temperatures (,and °C), and hot compression tests of samples in a wide range of temperature (– °C) and strain rate (–10 s−1) were conducted.

It was found that the initial austenite grain size Cited by: 6.

The application of jigs and fixtures in manufacturing operations lead to the production of faster, more accurate, and reliable products at a reduced cost.

Jig. A jig is a work-holding device that supports, holds, locates a work-piece and also guides the cutting tool for the desired machining operations. In hot forging processes, the factors affecting die life are thermal fatigue, plastic deformation and wear. Among these, wear is the main failure cause in hot forging dies.

Cser et al. [8] reported that die life in forging process is affected by wear in over 70%. The lifetime of hot forging dies is often shortened by surface cracking and subsequent.
