A High-Throughput Forging Technique and Its Application in the Optimization of the Deformation Conditions

Abstract

Abstract The high-throughput (HT) forging technique is introduced for speeding up the research on the forming property of materials. The core concept of the HT forging technology is to assign two influencing factors to multiple samples simultaneously. By se4tting gradients with different factors in the vertical direction and the horizontal direction, all the samples will be forged at different deformations and HT experimentation will be achieved. HT forging equipment was designed and developed to accomplish the 5 by 6 HT experimentation by establishing a temperature gradient in the vertical direction and a strain or a strain rate gradient in the horizontal direction. A simplified experiment with 5CrNiMoV steel to verify the reliability and efficiency was carried out. Combined with the analysis of microstructure, the relatively excellent deformation condition for the steel was the temperature of 1,000°C and strain rate of 1s−1. For obtaining the optimum deformation condition, more specimens should be forged in the HT equipment. It evidenced that the HT forging technique and the HT equipment would be favorable for analyzing the property and optimize the forming process rapidly.
