摘要
軌道工程中道岔是引導列車變換行車方向之元件，其重要性及安全性不言而喻，再者，

道岔磨耗甚鉅，因此期望藉由高錳鋼材料耐衝擊、擠壓、磨耗的特性以減少完工後營運期間
之維修頻率並提高行車安全，也期望藉由本文，能讓國內更多相關單位了解高錳鋼岔心，繼
而提升國內軌道工程視野、提升軌道工程品質。

關鍵詞：高錳鋼岔心、奧氏體、加工硬化、水韌處理

Abstract

The turnout, which guides train directional changes, is an important component associated with
major safety concerns. Since it is prone to wearing out, the turnout is made of high manganese steel
materials that resist impact, compression, and abrasion. This reduces maintenance frequency and

improves operational safety.
This paper aims to help domestic agencies understand more about high manganese steel frogs.
It will broaden trackwork vision and enhance trackwork quality.

Keywords: high manganese steel frog, austenitic, work hardening, water toughening treatment
