In order to solve some problem of stress sensor in dynamic weigh rail, a new kind of inductive stress sensor based on magnetostriction effect of amorphous alloy was developed. First, the principle of sensor, and inferred its output equation were discussed. Second, the static characteristic experiment and the actual experiment on the material testing machine and the mine haulage rail were separately made. The results of the test have showed that this stress sensor has some characteristics as high measurement sensitiveness and accuracy. Also being simple, convenient and solid to install and use, so it is feasible to apply the sensor for the dynamic weigh rail.

A new correction instrument of pectus excavatum is introduced which is designed for a minimally invasive technique (Nuss procedure). The instrument was made of pure titanium plates, and finished by machining, surface treatment and so on. The instrument was made up of correcting bar and fixing bar. The mechanical properties of the instrument was measured with electron universal material testing machine, the safety and validity was verified by clinical doctors after being implanted into the patient. Results showed that the mechanical properties of the instrument keep constantly after implantation for two years. It is lighter than the like product, and can lighten the patent’s and the doctor’s operation bearing. It had been applied in national hospitals, and results showed that it was of better biocompatibility, and few complications were found. Clinical treatment effects were satisfactory.

The crystal morphology, melt-crystallization and mechanical properties of poly (trimethylene terephthalate)/maleinized poly (octene-ethylene)/organo-montmorillonite nanocomposites were investigated by using polarized optical microscopy (POM), differential scanning calorimetry (DSC) and universal material testing machine, respectively. The results suggest that the nanocomposites form smaller or imperfect microcrystallites with lower melting point due to the influence of OMMT components and the nanocomposites have increased crystallization rate because OMMT is an effective nucleation agent. However, the crystallinity decreases because of the thickening effect of OMMT in the composites. The nanocomposite with 2%OMMT has the largest tensile and impact strength.

TRIP steel possesses excellent mechanical properties dominated by strain-induced martensitic transformation (SIMT). For automotive industries, if TRIP steel can be applied to shock absorption members, it can be considered that the weight of automobile can be reduced. However, the strain rate sensitivity of TRIP steels has not been fully understood because the strain rate sensitivity and the deformation mode dependency of SIMT are still unclear. Therefore, it is important to reveal these sensitivity and dependency for confirming a reliability of TRIP steel. Therefore, in this study, it is attempted to estimate the amount of produced martensite in TRIP steel by measuring the inductance of TRIP steel. The specimen made of TRIP steel is used as a core of a prototype coil manufactured in this study. Then, the compressive and tensile tests are conducted by using a material testing machine and a drop weight testing machine using the specimen inside the coil. The inductance of the coil with the deformed specimen are measured continuously during the tests.

by using connection type I. To get a good welding result is determined several factors, including the properties of material welding, connection type, welding position, and electrode used. In a welding project, there is still a welder that only uses I in the weld IWF 400 connecting iron while the thickness of the material 13 mm. This study aims to determine the effect of the use of campuh against the strength of weld joint connection using LB 52U 2.6 mm Electrode and RD 7018 3.2 mm electrode with AC Flow. In this study using experimental method begins with making specimens. With the collection of 7 specimens consisting of 3 specimens with welding treatment using Camp V, 3 specimens with welding treatment using Camp I and 1 IWF 400 specimens without welding treatment. From the results of research conducted on specimens by making and testing specimens with a tensile test machine Hydraullic Universal Material Testing Machine then obtained on the specimen without welding average value of Maximum (max) 41,28 kgf/mm². In welded specimens with a connection of the V values the average value of the Maximum (max) 39,82 kgf/mm². On a welded specimen with a maximum I knot connection (max) 38,32 kgf/mm².The results of this study indicate the results of iron welding IWF 400 using camp V greater value voltage 39.82 kgf / mm². From the maximum voltage value obtained from this study it is recommended that iron welding IWF 400 uses V.
