对组分梯度功能范围的调整要求已提出,通常通过不同材料组合得以解决。但是这种生产方式一方面需要一系列的工序,另一方面也需要具体的知识,包括所用材料的独特物理及机械特性,尤其是它们的形变及热行为。因此,为了降低能耗,考虑到生态需求,一个组分的现代工业设计程序只应包括一种操作程序和一种具有优化性能的范围大的材料。同时对同质的工件初样进行热处理及机械处理保证了控制材料能够具有最终元件性能的梯度功能。第一步,研究不同热处理对CrV-合金热处理矩形条钢(51CrV4)微观结构演化的影响。生产出只具有铁素体-珠光体、铁素体-珠光体-贝氏体和马氏体结构的条钢。与振动的振幅衰减相关的时间由声学照相机测定。这种声学照相机可以产生彩码声音图谱,显示覆盖于已记录样品图像上噪音的强度和来源。基于作为常规信号处理方法的波束形成概念,该声音分析用来控制换能器阵列上信号的接收或传播方向。条钢的独特微观结构状况造成了振动特性的显著变化。
Adjustments to the functional scope of component gradients have been made and are often addressed by different material combinations. However, this method of production requires a series of processes on the one hand and also requires specific knowledge on the other hand, including the unique physical and mechanical properties of the materials used, in particular their deformation and thermal behavior. Therefore, in order to reduce energy consumption, taking into account the ecological needs, a component of the modern industrial design program should include only one operating procedures and a range of materials with optimized performance. At the same time, the homogeneous treatment of the initial sample heat treatment and mechanical processing to ensure that the control of the material can have the final element performance gradient function. In the first step, the effects of different heat treatments on the microstructure evolution of the CrV-alloy heat-treated rectangular strip (51CrV4) were investigated. A strip of steel having only ferrite-pearlite, ferrite-pearlite-bainite and martensite structures was produced. The time associated with the amplitude attenuation of vibrations is determined by an acoustic camera. This acoustical camera can produce a color code sound pattern showing the intensity and source of the noise overlying the recorded sample image. Based on the beamforming concept as a conventional signal processing method, this sound analysis is used to control the direction of signal reception or propagation on the transducer array. The unique microstructural condition of the bar creates a significant change in vibration characteristics.
