About our Lab

　　Welcome to the Key Laboratory of Liquid Structure and Heredity of Materials Web pages. Our Lab became an autonomous university-level institution under the Ministry of Education in 2000. It is constituted from the existing Colleges of Materials Engineering and Technology at Shandong University of Technology, Casting, Welding and Ceramic. It provides third-level education to some 2,000 students making it the first such establishment in China. The Institute is currently being restructured on a faculty basis. As such the Key Laboratory plays a leading role in liquid structure and heredity of materials in China. Its technological strengths are centred in the faculties of Engineering, Materils and Physical Science . It has also a substantial involvement in the area of Applied research.

　　It is closely involved with the latest developments in technology in Aluminum alloy, while maintaining a continuing commitment to industrial development.

research field

　　The lab, which combines the examination tests with computer simulation to research the transport properties of electron and atom, changes of atom space and approximate solution Boltzmann calculus equation in liquid metal, aims to establish models about physical properties and structure of liquid metal. According the relationship between melt structure and formability of amorphous and quasicrystalline, the formula criterion of formability, which includes the variables of melt structure and situation, is estimated. The lab also investigates the changes of physical properties in solid-liquid system, activity and exist forming of hydrogen in the Al melt and the relationship between melt structure and solubility of hydrogen in liquid melt.
　　It should be studied and mastered in metal Solid-liquid-solid transformation, the rule of heredity among microstructures, the atomic-leveled heredity essence and the mechanism of strengthening and toughening in composites. Requirements and the regulation of controlling the quality of the melt material and raw material should be put forward in the perspective of heredity. It is considered to obtain an improvement in the technology of preparing materials with good mechanical, multifunction, intelligent or other unique properties.
　　The theory of mechanism and toughening in intermetallic compound-matrix-ceramics composite and ceramics-matrix-intermetallic compound composite will be studied in the field of electronic structure, which results the establishment of a crystallographic model in the new type of composite. In this research, the theory of heredity and modern methods of examination and calculation need to be adopted. With the purpose of improving the academic design in new materials, a set of new software should be programmed, by which microstructure and macro properties of new materials could be estimated in advance. A large increase in toughness should be realized by the method of preparing nanometer- or micron- structured composites. The composites with good mechanical properties will be the substitute for import materials being applied in the production of cold dies, military wares, cutting tools, painting materials etc. The accomplishment of application will bring in a considerable benefits.
　　All that to study the effects which welding parameters bring about on the formation of new phase at the diffusion interface, to analyze the formation and the growth rule of the new phase, to put forward geometrical models of the physical contact interface and area models of the joining interface about the diffusion welding, to build up a model of atom action thermodynamics and a dynamics model, and to simulate atom's dynamic diffusion behavior during the diffusion welding process through the diffusion welding between the same or the different new material, for example Fe3Al,Ti/Al,Mg/Al and so on. It is helpful for the quantitative analysis of the atom's diffusion distance at the diffusion interface, determining the new phase structure at the diffusion interface, analyzing the capability of the welding joint effectively and simply, and the theory of the optimization for welding parameters.
