Çeliğin Çevresel Sürdürülebilirlik ve Genel Refah İçin Çok Yönlü ve Ekonomik Katkıları

Abstract

Çelik, maliyet etkinliği ve çok yönlülüğüyle tanınan bir metalik malzemedir. Araştırmacılar, sürekli olarak üstün mekanik özelliklere sahip yeni metalik malzemeleri incelemektedirler. Özellikle, hafif tasarımın önem kazandığı mühendislik uygulamalarında, alüminyum, magnezyum ve titanyum gibi geleneksel metalik malzemeler tercih edilmektedir. Ancak, çekme-yorulma sonucu kullanılamaz hale gelen çelik ve düşük yoğunluklu paslanmaz çelik gibi malzemelerin, yeni geliştirilmiş metalik malzemelerle rekabet edebilecek potansiyeli bulunmaktadır. Bu makalede, bu malzemelerin yeniden kullanımıyla ilgili deneysel sonuçlar sunulmakta ve çeliğin, mevcut ve yeni geliştirilmiş malzemelerle rekabet edebilecek düzeyde bulunduğu savunulmaktadır. Ayrıca, çeliğin bulunabilirliği, çok yönlülüğü ve ekonomikliği ön plana çıkarılarak, çeliğin önümüzdeki yıllarda da önde gelen metalik malzeme olmaya devam edeceği ifade edilmektedir. Bununla birlikte, çeliğin çevresel sürdürülebilirlik ve yaşlanan nüfusun genel refahına nasıl katkı sağladığına dair örnekler de sunulmaktadır. Bu çalışma, çevresel sürdürülebilirlik ve genel refah gibi önemli hedefler doğrultusunda Birleşmiş Milletlerin sürdürülebilir kalkınma gündemine katkı sağlamaktadır.

Exploring the Versatility and Affordability of Steel for Environmental Sustainability and Overall Well-Being

Abstract

Steel, being the most versatile and cost-effective metallic material, has been scrutinise by researchers as new metallic materials with superior mechanical properties continue to emerge. Moreover, conventional metallic materials such as aluminium, magnesium, and titanium have been favoured in various engineering applications where lightweight design is crucial. This paper presents experimental results on the reuse of creep-exhausted steel and low-density stainless steel, highlighting their potential to compete with existing conventional metallic materials or newly developed ones like high entropy alloys. The paper argues that steel's availability, versatility, and affordability will continue to position it as the leading metallic material in the years to come. It also provides examples of how steel contributes to environmental sustainability and the overall well-being of the geriatric population. Environmental sustainability and overall well-being are prominent goals within the United Nations' sustainable development agenda.
