Abstract

We investigate the tensile deformation behavior and mechanism of nickel-based superalloy CM247LC, which has been subjected to various ageing treatment schemes, but possesses almost the same γ′ particle size, at 600°C. It is found that the transition in the deformation mode from particle shearing plus microtwinning to particle shearing accounts for the decrease in the work-hardening rate and tensile strength with ageing temperature. Our study provides a new strategy to design the heat treatment schedule to achieve a good compromise between the strength and plasticity for superalloys by tunning the operative deformation and fracture mechanisms.

通过调整时效处理,调整镍基高温合金CM247LC的拉伸变形行为和机理
研究了经过多种时效处理的镍基高温合金CM247LC在600℃下的拉伸变形行为和机理,该合金具有几乎相同的γ′晶粒尺寸。研究发现,随着时效温度的升高,加工硬化率和抗拉强度下降的主要原因是由颗粒剪切+微孪晶向颗粒剪切变形模式的转变。本研究为设计热处理方案提供了一种新的策略,通过调整高温合金的操作变形和断裂机制,实现高温合金强度和塑性的良好平衡。

期刊介绍: Materials Research Letters is a high impact, open access journal that focuses on the engineering and technology of materials, materials physics and chemistry, and novel and emergent materials. It supports the materials research community by publishing original and compelling research work. The journal provides fast communications on cutting-edge materials research findings, with a primary focus on advanced metallic materials and physical metallurgy. It also considers other materials such as intermetallics, ceramics, and nanocomposites. Materials Research Letters publishes papers with significant breakthroughs in materials science, including research on unprecedented mechanical and functional properties, mechanisms for processing and formation of novel microstructures (including nanostructures, heterostructures, and hierarchical structures), and the mechanisms, physics, and chemistry responsible for the observed mechanical and functional behaviors of advanced materials. The journal accepts original research articles, original letters, perspective pieces presenting provocative and visionary opinions and views, and brief overviews of critical issues.
