To perfect the discipline system of safety materials science,guide and promote the research of safe-ty materials science,the definition of methodology of safety materials science is put forward and the theoretical basis is discussed.Then,the research of safety materials science is divided into three phases,that is materials safety, phenomenon-materials safety and law-materials safety science,and its general research methods are argued.The features of methodology of safety materials science are summarized,a six-dimensional structure system of the meth-odology of materials safety science is founded,and the connotation of each dimension is elaborated.On this basis, the practice steps and methods of safety materials science are put forward by using “before accidents-during acci-dents-after accidents”as overall thinking.The results show that the hierarchical thinking of safety materials science research is systematized,and the results can provide theoretical guidance for the research and application of safety materials science.%为完善安全物质学的理论体系，指导并促进安全物质学研究与应用的开展，提出安全物质学方法论定义，论述其学科基础和理论基础。提出安全物质学研究三阶段：物质安全现象－物质安全规律－物质安全科学，并阐述其一般研究方法。归纳安全物质学方法论特征，建立安全物质学方法论六维结构体系，分别解析各维度内涵。基于此，以“事前－事中－事后”为主线厘清安全物质学研究的实践程序，并提炼具体实践方法。研究结果系统化了安全物质学研究的层次思路，可为安全物质学的研究和应用提供理论指导。
