838 Generating the Microstructure of Al-Si Cast Alloys Using Machine Learning
기계학습에 의한 Al-Si 주조 합금 미세조직 이미지 생성
In-Kyu Hwang, Hyun-Ji Lee, Sang-Jun Jeong, In-Sung Cho, Hee-Soo Kim
황인규, 이현지, 정상준, 조인성, 김희수
Korean J. Met. Mater. 2021;59(11):838-847.   Published online 2021 Oct 28
DOI: https://doi.org/10.3365/KJMM.2021.59.11.838

In this study, we constructed a deep convolutional generative adversarial network (DCGAN) to generate the microstructural images that imitate the real microstructures of binary Al-Si cast alloys. We prepared four combinations of alloys, Al-6wt%Si, Al-9wt%Si, Al-12wt%Si and Al-15wt%Si for machine learning. DCGAN is composed of a generator and a discriminator...... More

430 Mid-Layer Visualization in Convolutional Neural Network for Microstructural Images of Cast Irons
주철 미세조직 분석을 위한 합성곱 신경망에서의 중간층 시각화
Hyun-Ji Lee, In-Kyu Hwang, Sang-Jun Jeong, In-Sung Cho, Hee-Soo Kim
이현지, 황인규, 정상준, 조인성, 김희수
Korean J. Met. Mater. 2021;59(6):430-438.   Published online 2021 May 26
DOI: https://doi.org/10.3365/KJMM.2021.59.6.430

We attempted to classify the microstructural images of spheroidal graphite cast iron and grey cast iron using a convolutional neural network (CNN) model. The CNN comprised four combinations of convolution and pooling layers followed by two fully-connected layers. Numerous microscopic images of each cast iron were prepared to train and..... More

184 Estimation of Chemical Composition of Al-Si Cast Alloys Using Image Recognition
화상인식을 이용한 Al-Si 주조용 합금의 화학조성 예측
Sang-Jun Jeong, In-Kyu Hwang, In-Sung Cho, Hee-Soo Kim
정상준, 황인규, 조인성, 김희수
Korean J. Met. Mater. 2019;57(3):184-192.   Published online 2019 Feb 14
DOI: https://doi.org/10.3365/KJMM.2019.57.3.184

In this study, we analyzed the chemical composition of Al-Si cast alloys from microstructural images, using image recognition and machine learning. Binary Al-Si alloys of Si = 1~10 wt% were cast and prepared as reference images in the dataset used for machine learning. The machine learning procedure was constructed with..... More
