Thermal—Mechanical Fatigue Behavior and Life Analysis of Cast Ni—base Superalloy K417

In-phase(IP) and out-of-phase(OP)thermal-mechanical fatigue(TMF) behavior of cast Ni-base superalloy K417 was studied.All experiments were carried out under total strain control with temperature cycling between 400-850℃.Both in-phase and out-of-phase TMF specimens exhibited cyclic hardening followed by cyclic softening at the minimum temperature.Besides,they cyclically hardened in the early stage of life followed by cyclic softening at the minimum temperature.Besides,they cyclically hardened in the early stage of life followed by cyclic softening at the maximum temperature.OP TMF life was longer than of IP TMF.Various damage mechanisms operating in different controlled strain ranges and phasing were discussed.A few life prediction methods for isothermal fatigue were used to handle TMF fatigue and their applicability to superalloy K417 was evaluated.The SEM analysis of the fracture surface showed that transgranular fracture was the principal cracking mode for both IP and OP TMF.Oxidation was the main damage mechanism in causing shorter fatigue life for IP TMF compared with OP TMF.

In—situ Composite Based on Poly （ethylene terephthalate）,Polyamide and Polyethylene with Microfibres Formed through Extrusion and Hot Stretching

In-situ composites based on dispersed poly (ethylene terephthalate) (PET) or polyamide (PA),and continuous Polyethylene (PE) were prepared through a single screw extruder of Haake rheometer system with a rod-die relatively small in diameter.The extrudate was drawn at a drawing ratio of 3.1,and then quickly cooled in cold water.The specimens were obtained by injection molding at processing temperatures less than 190℃，far below the melting temperature of PET (265℃) and PA (230℃),which can maintain the solid state of PET and PA microfiber phase in the composites.Morphological observation with scanning electron microscopy (SEM) indicated that PET and PA can more or less form in-situ microfibers at compositions studied (0-20 wt pct PET or PA),and especially,PET and PA were almost deformed into fibers at the concentration of 15wt pct.Eensile strength and especially.PET and PA were almost deformed into fibers at the concentration of 15wt pct.Tensile strength and modulus of the blends reinforced by PET or PA microfibers showed to be increased from the tensile test results.The most noticeable improvement of the tensile properties occurred at 15wt pct of PET in PET/PE system,corresponding to the highest microfiber content,where the tensile strength reached 32.5 MPa,whereas only 19.5 MPa for the pure PE.

加氢润滑油基础油光安定性研究进展

加氢处理基础油与溶剂精制基础油相比具有硫、氮含量低，颜色浅，粘度指数高，挥发性低，饱和烃含量高，对添加剂的感受性好等优点。但是，加氢处理润滑油基础油的一个明显缺点就是其光安定性差，即在有氧条件下通过光照（有时也需加热），油品颜色加深、透明度变差，继而有絮凝物或沉淀生成。文章综述了国内外有关加氢润滑油基础油光安定性的原因和解决办法的研究进展情况。     

回采巷道锚杆支护的研究

0 前言 鹤岗矿务局属国有大中型煤炭企业,煤层赋存多属中厚煤层、厚煤层,全年回采掘进总延米12万m左右(其中一分层巷道占20%,假顶下巷道占80%),随着综采、综放、高档普采等技术的发展,高产、高效工作面要求顺横断面加大,工作面推进速度的加快,使传统的木棚、工字刚棚以无法适应"高新"技术的要求,因此进行回采巷道支护改革势在必行,长期以来,该局在回采巷道支护上一直使用木棚、工字钢、U形钢等支架,以上支架在使用上存在问题较多,最大的缺点是不能有效的控制围岩的破胀力,支架没有初撑力,是一种被动支护,不能发挥巷道围岩的自撑能力.单体液压支架和摩擦支架虽有初撑力,但对两帮的水平应力无明显的支护作用,因此研究解决回采巷道支护是该局生产的当务之急.
