Numerical Investigation on Semisolid Closed-Die Forging of 6061 Aluminum Alloy Scroll Plate Based on the Arrhenius Constitutive Model

2026-99-0836

7/30/2026

As a key structural component of scroll compressors, the forming quality of the scroll plate directly affects overall performance. To address the issues of high forming load and poor rib filling in conventional processes, this study investigates the semisolid closed-die forging of 6061 aluminum alloy through numerical simulation. Semisolid rheological data were obtained from high-temperature compression tests. We also formulated an Arrhenius-type constitutive model to predict material behavior. This model proved highly reliable, achieving a correlation coefficient of 0.99547 and keeping the average absolute relative error down to 3.67%. By employing both orthogonal experiments and simulations, we evaluated how different process parameters impacted the outcome. This analysis ultimately yielded an optimal parameter combination: a die temperature of 350°C, a billet temperature of 600°C, and a punch velocity of 10mm/s. Under these conditions, the forming load, flow behavior, stress–strain distribution, and temperature evolution were analyzed. The results show complete rib filling, uniform deformation, and absence of defects, providing theoretical guidance for industrial applications of semisolid closed-die forging of scroll plates.

Development of Integral Forming for New “NMAX” YECVT Parts Using the Plate Forging Method

2025-32-0005

11/3/2025

Yamaha Motor Engineering Co., Ltd. provides plastic processing technology based on fuel tank press forming technology, and is developing various plastic processing methods, including forging, and developing mold equipment to realize them. This time, the core parts of the YECVT unit mounted on Yamaha Motor Co., Ltd.'s small premium scooter "NMAX" were not made by welding individual parts to each other, but by integrally forming them from a single thick plate using the cold forming method, resulting in lightweight, compact, high-strength, high-precision parts. By incorporating a composite plastic processing method that takes advantage of the characteristics of the material while making full use of analysis technology and mold technology, we were able to develop a composite plastic processing method (plate forging method) that creates new added value and mass produce it. In addition,this development has made it possible to achieve a thickness increase of 1.7 times the standard material thickness as a mass production method.
