The invention discloses a nickel-based high-temperature alloy high-throughput sample with continuously changed element content and a preparation method thereof. The sample has continuous 1-3 alloy element gradients in a range of 200-600 microns at an interface; the high-throughput sample can be used for accurate research and parameter optimization of alloy high-temperature oxidation performance, heat treatment process, mechanical property and the like in a target element content range. According to the preparation method, a plurality of samples with single target alloy element content do not need to be prepared firstly, then the influence of the element content on the alloy performance is detected one by one, and the preparation method has the advantages of being simple in process, high in efficiency, low in cost and accurate in characterization result. 本发明公开了一种元素含量连续变化的镍基高温合金高通量样品及其制备方法，样品在界面处200-600微米范围内存在连续的1-3种合金元素梯度；该高通量样品可用于目标元素含量范围内的合金高温氧化性能、热处理工艺、力学性能等的精确研究及参数优化。本发明的制备方法，不再需要先制备多个单一目标合金元素含量的试样，再逐个检测元素
