摘要

摘要:本文研究了屈服点不小于420mpa的低合金造船用钢轧制至100mm厚的薄板的组织和性能变化。研究了低温冲击弯曲试验后试样的断口形貌。研究发现，板条形态贝氏体参数(分数、面积平均尺寸和长度)和结构元件在给定公差角为5°和15°时的尺寸(表明是否存在发育的变形源亚晶组织)的组合决定了低温试验中冲击工作的水平。

Heterogeneity of Structure and Mechanical Properties Studied in Thickness up to 100 mm of Low-Alloy Shipbuilding Steel Sheets with a Yield Strength Not Less Than 420 MPa

Abstract—This paper presents a study of changes in the structure and properties in thickness of rolled sheets up to 100 mm of low-alloy shipbuilding steel with a yield point not less than 420 MPa. The fracture surface of samples after impact bending tests at low temperatures was investigated. It was found that the combination of the parameters of lath morphology bainite (fraction, areas average size and length) and the size of structural elements at given tolerance angles of 5° and 15° (indicating the presence or absence of a developed subgrain structure of deformation origin) determines the level of impact work at testing at low temperatures.

期刊介绍： Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
