Introduction

1. Standard Overview

GB/T 37783-2019 "Method for high strain rate and high temperature tensile test of metallic materials" specifies the method of high temperature and high strain rate tensile test of metallic materials using a split Hopkinson tension bar, including terms and definitions, symbol descriptions, test principles, equipment requirements, specimen preparation and data processing.

2. Background of Standard Formulation

With the increasing demand for material performance in modern engineering, it has become particularly important to evaluate the mechanical behavior of metallic materials under extreme conditions (such as high temperature and high strain rate). The formulation of this standard aims to provide a unified test method for scientific research and industrial applications to ensure the accuracy and comparability of data.

3. Comparison of standard frameworks

Standard dimensions	GB/T 37783—2019	International general standard
Test equipment	Split Hopkinson bar system	Widely uses Hopkinson bar technology
Temperature range	Above room temperature, up to 1100°C	Typically covers high temperature environments
Strain rate	$10^{2} s^{-1} \sim 10^{3} s^{-1}$	Consistent with dynamic test

4. Implementation suggestions

Data acquisition system: Ensure that the sampling frequency is not less than 1 MHz and calibrate the equipment to meet the accuracy requirements.

Temperature control: Use a combined heating device and strictly monitor the cold contact time not exceeding 100 ms.

Specimen preparation: Select the appropriate specimen shape and size according to the material characteristics, and ensure that the parallel length meets the standard requirements.
