TY - JOUR ID - 33251 TI - Study Relationship Between The Dimensional Change – Temperature and Carburizing Time of Low Carbon Steel By Using (C#2008) Programming Language JO - Engineering and Technology Journal JA - ETJ LA - en SN - 1681-6900 Y1 - 2011 PY - 2011 VL - 29 IS - 15 SP - 621 EP - 634 DO - 10.30684/etj.29.15.19 N2 - In this paper a program was build by (C#2008) programming language to calculate a dimensional change in specimens of low carbon steel during solid carburizing process. The chemical composition, mechanical properties and microstructure for all specimens was the same. Carburizing process was done in different temperatures ( 850 , 900 and 950 ) oC for holding times of ( 3 , 6 and 8 hours ) respectively flowed by normalizing , quenching and tempering to improve mechanical and microstructure properties. The specimens was measured dimensionally with high accuracy before and after mentioned above heat treatments processes to identify the change in dimensions due to change in phases of the surface layer of metals during martenstic transformation. Briefly this work is useful in determining the right dimensions of parts before applying heat treatments to obtain the final desired dimension of the final product.
