The effects of process parameters of laser additive manufacturing (laser power, scanning speed, scanning direction) and heat treatment on the microstructure and properties of Ti-6Al-4V titanium alloy forming parts were studied under coaxial powder feeding. The results show that the columnar crystals of the Ti-6Al-4V forming parts made by laser material are all wechsler structure, and there are obvious layers in the layer; the strength of laser reinforced Ti-6Al-4V titanium alloy parts exceeds the requirements of national standard for as cast and forged Ti-6Al-4V titanium alloy; With the increase of laser power, the tensile strength and yield strength of Ti-6Al-4 V titanium alloys tend to increase first and then decrease, and the maximum value is obtained when the laser power is 500 W; when the scanning speed increased from 0.12 m/min to 0.60 m/min, the tensile strength and yield strength of the Ti-6Al-4V titanium alloy showed a gradual decrease, but the elongation gradually increased; when the laser scanning mode is changed from single sweep to round-trip scanning, the tensile strength and yield strength of Ti-6Al-4V titanium alloy have been improved, but the elongation has decreased significantly. Through the solution and aging heat treatment at 950 degrees C/AC/1 h+ 540 degrees C/AC/4 h, the original wechsler structure can be improved and the high performance net basket organization can be obtained, this is the fundamental reason for improving the comprehensive performance of the forming parts.

The electrode of hydrogen storage Mm10.3Ml0.7Ni3.55Co0.75Mn0.4Al0.3/x wt％ Ni alloy was prepared by different methods.In the patch-type three electrode system,the activation performance,discharge capacity,high rate discharge capacity of the electrodes was investigated by electrochemical methods.The results show that the discharge capacity of 5 parallel samples prepared by the dry process were higher than those of samples prepared by the wet process and the activation is also fast.Hydroxyl nickel powder in the electrode can effectively reduce the numbers of activation.The maximum discharge capacity of the electrode increases with the increase of the content of hydroxy nickel powder in the as-designed range.The discharge capacity of the corresponding electrode is 300～344 mAh/g,which increases by 3.8％ ～19.0％ compared to the electrodes prepared by the wet process.The addition of hydroxyl Ni powder with different mass fraction can effectively improve the high rate discharge capability of the alloy electrode under different high current discharge.Furthermore,discharge characteristics is the best at Mm0.3Ml0.7Ni3.55Co0.75Mn0.4Al03/200 wt％Ni electrodes.

The effects of the content of modified SiO2 on the viscosity,volume shrinkage,gel ratio,tensile strength and microstructure of light cured 3D printing resin were studied,and the corresponding mechanism was analyzed.The results show that with the increase of the concentration of modified SiO2,the viscosity of composite light cured 3D printing resin gradually increase,and the gel rate increase at first and then decrease,and get the maximum gel ratio when the content of modified SiO2 is 1.5％.When different amounts of modified SiO2 are added,the temperature is almost the same or decrease slightly when the weight loss is 10％,while the residue at 700 ℃ show a trend of increasing gradually.When the content of modified SiO2 is 1.5％ and 3％,the compound light cured 3D printing resin can obtain higher tensile strength,which is mainly related to the size distribution of particles and the dispersion of SiO2 particles in composite 3D light curing resin.

The welding of 2524 aluminum alloy was carried out by using PLC to control the laser welding process parameters, and the effects of laser power, welding speed and wire feeding speed on the hot crack tendency and microstructure of welded joint were studied. The results show that with the increase of laser power, the total number of welding cracks increases. The weld center is equiaxed dendritic structure, and the weld near the fusion line is columnar crystal structure. The average grain size of weld center and columnar crystal spacing of the weld near the fusion line increase. With the increase of welding speed, the total number of cracks in welded joint and the hot crack tendency increase, and the weld width and weld area reduce. With the increase of wire feeding speed, the total number of cracks in welded joint decreases. After welding with filler wire, the formability of the weld is better than that of self welding, and the weld area increases obviously.
