用感应熔炼法制备了一系列添加少量C、Si和Mn的小铁样，并用高通量方法对其进行了表征。其目的是分析高产量方法本身，而不是对钢铁进行少量添加的影响。尽管它们的尺寸很小，但测量的标准机械性能的趋势与公布的数据是一致的，目标合金成分达到了足够的精度。这是最令人鼓舞的，因为这里描述的实验方法在非常短的时间范围内交付了结果，每个成分的时间估计为<； 2 h每个样品。这种方法似乎是工业中使用的更传统、更昂贵和更耗时的合金开发方法的一个极好的先驱。描述了该方法的局限性，并确定了关键瓶颈。然而，使用小样本来量化钢的性能趋势并确定可能的新合金对新钢的开发具有潜在的价值。
A series of small iron specimens with minor additions of C, Si and Mn were manufactured via induction melting and characterised using a high throughput methodology. The aim was to analyse the high throughput approach itself, not the effects of minor additions to steel. Despite their small size, the trends in measured standard mechanical properties were consistent with published data, and target alloy compositions were achieved to a sufficient degree of accuracy. This is most encouraging as the experimental approaches described here delivered results in a very short time frame, with time per composition estimated to be < 2 h per sample. Such an approach would appear to be an excellent precursor to more traditional, expensive and time consuming alloy development methods used by industry. Limitations of the methodology are described, and key bottlenecks are identified. However, the use of small specimens to quantify trends in properties of steels and identify possible new alloys is potentially a valuable addition to the development of new steels.
