This project aims to study the impact of temperature annealing process on the microstructure and mechanical properties of abrasion resistant high chrome cast iron to produce blades loosening the soil for rice. By annealing at 650, 750, 850, 950 ° C, baking time infusion 5 hours, then taken to monitor and analyze the microstructure. And mechanical properties
test results showed that annealing blade loosening the soil to a temperature of 950, 850, 750, 650 ° C for a period of a soak five hours showed that the blade disc surface hardness decreased from. supplied with hardness average 584.9 HV consists of a chromium carbide type (Fe, Cr) 7C3 with carbide type Eutectic and ferrite powerful applications, which corresponds to the value. hardness And wear resistance For practical use
