【摘要】

：

随形冷却模具一般具有复杂的异形流道,能够大大提高冷却效率和产品的表面质量,但是其加工难度非常大.增材制造是一种通过逐层累加实现构件成形的技术,其优势是能实现材料的内部复杂结构.粉末的制备是增材制造的基础也是关键步骤,粉末质量的高低一定程度上决定了增材件的好坏,常见的模具钢粉末制备方法有气雾化法和等离子旋转电极雾化法.增材制造时材料将会经历快速熔化和快速凝固的过程,同时还要经受层间热循环的作用,其组织和微观结构严重偏离平衡凝固时的组织和结构.模具钢增材体的抗拉强度和屈服强度一般高于铸造态母材、低于轧制态或固

Highly sensitive luminescent lanthanide metal-organic framework sensor for L-kynurenine

L-kynurenine (L-kyn) is a marker of prostate cancer.At present,the expensive instruments are usually applied to detect L-kyn clinically,which limits its wide application for cancer diagnosis.Herein,three lanthanide metal-organic frameworks ([Ln(CHO2)3]n,L

Structural,magnetic,electrical and microwave properties of spinel ferrites

The ferrite series having formulation SrYbyFe2-yO4 (y =0.00 to 0.10) were synthesized via the sol-gel procedure.The involvement of the yttrium in the base produces several changes in the structural,magnetic,and electrical performance of the system.Investi
