教育及工作经历（含交大材料学院）

教师简介

梁强龙副教授于2020年11月加入西安交通大学材料学院强度室丁向东教授“材料相变与形变”研究团队。梁强龙副教授长期致力于形状记忆合金中马氏体相变的微观结构起源、限域调控机制及循环稳定功能优化开展系统研究，围绕“相变机理—微结构设计—功能稳定化”构建了系统性研究框架，在纳米尺度连续相变机制、孪晶与界面结构调控以及抗功能衰减材料设计等方面形成了持续深入且具有原创性的研究积累。针对传统马氏体相变以突发、自催化转变为主导的经典认识，研究并系统发展了“纳米尺度连续相变”与“限域相变调控”新范式，显著提升了形状记忆合金宽温域与高周循环稳定性。相关成果以第一/通讯作者在Nature Communications、Acta Materialia、Scripta Materialia、Materials Research Letters及Physical Review Materials等国际高水平期刊。

Dr. Qianglong Liang joined the research group “Phase Transformation and Deformation of Materials,” led by Professor Xiangdong Ding at the School of Materials Science and Engineering, Xi’an Jiaotong University, in November 2020. Dr. Liang has long been dedicated to systematic research on the microstructural origins of martensitic transformations in shape memory alloys, mechanisms of confined regulation, and optimization of cyclic functional stability. Centered on the framework of “phase transformation mechanisms – microstructure design – functional stabilization,” he has established a coherent research system and developed sustained, in-depth, and original contributions in areas such as nanoscale continuous phase transformation mechanisms, twin and interfacial structure regulation, and the design of materials resistant to functional degradation. Challenging the classical view that martensitic transformations are dominated by abrupt and autocatalytic processes, he has investigated and systematically developed new paradigms of “nanoscale continuous phase transformation” and “confined phase transformation regulation,” significantly enhancing the wide temperature range applicability and high-cycle stability of shape memory alloys. His related research have been published as first or corresponding author in leading international journals, including Nature Communications, Acta Materialia, Scripta Materialia, Materials Research Letters, and Physical Review Materials.
