     KOLAS and Nadcap(Korea's 1^st)
 • Development of Accelerated Life Test Methods
     considering practicalapplied environment based on
     reliable test infrastructure of Fatigue,Creep, and Wear
     analysis

Failure analysis based Quality Enhancement

 • Failure Analysis: Intensive Support of Applicable
     Solutions based onin-depth analysis of in-field failures
     of base-materials and partsconsidering its applied
     environments
 • Development and Supply of Material DB: Material DB
     development andsupply for mechanical design and
     material selection (Microstructure/Chemical composit-
     ion/Mechanical properties(Tensile/Hardness/Impact
     testing) and Fatigue/Creep)

Corrosion evaluation technology for materials & parts

 • Equipment and technology to evaluate various
     corrosion phenomena suchas salt spray, pitting, crevice,
     electrochemical reaction, gas corrosion and soil
     environment test, etc
 • Supporting for effective anti-corrosion measures by
     evaluating thecorrosion testing
 • Providing reliable test evaluation service by acquiring
     KOLAS certification of standards and evaluating the life
     of materials & parts through corrosion acceleration test
     methods

Standard material production and evaluation technology

 • Standard material: A material with sufficiently homo-
     geneous and well-established property values used to
     calibrate the device, evaluate themeasurement method
 • Designated as the first domestic standard production
     organization in themetal field
 • Developed 18 types of certified standard materials and
     83 types ofprocess quality assurance standards based
     on related infrastructure

Trace elemental analysis

 • Quantitative analysis of major, minor and trace
     elements in various materials such as silica, alumina,
     silicon carbide, and high purity metalsby ICP-MS
 • Trace elemental microanalysis by Laser Ablation ICP-MS
      and LIBS
 • Impurity analysis in high purity materials by GD-MS

Laser Induced Breakdown Spectroscopy

 • Laser induced breakdown spectroscopy (LIBS) could be
     applied forelemental analysis in various samples
 • RIST have developed the LIBS system called ROSA (RIST
     Optical Spectroscopic Analyzer) REI-266 for elemental
     mapping in steel industry.
     REI-266 is fast and quantitative analysis LIBS system

The Characterization Technic for the Secondary Batteries

 • The service of in-situ analysis to be able to observe the
     phenomena onsurface/interface during the cycle test
     and to analyze the LIB materials in air non-exposure
     state
 • The analysis service of mechanism and degradation to
     interpret thereasons for high performance batteries
     (The Failure Analysis for LIBmaterials)

Analysis and Characterization of Steel

 • Research on the analysis and assessment of steel for the
     technical competitive strength and the products of high
     quality in POSCO
 • Microstructural characterization on high strength steel
     for automobile, galvanized steel for high corrosion
     resistance steel, and electrical steel
 • Development of technologies for the quality improve-
     ment of the analyticaldata on steel

AI-based steel microstructure automatic analysis technology

 • By using deep learning technology for quantitative
     analysis of microstructure, which is essential for
     the analysis of the relationship between the
     manufacturing process of steel materials and
     physicalproperties, it is easy to obtain a statistical
     representative value by analyzing multiple images
     faster than the existing analysis method.
     In addition, image recognition through pattern
     recognition makes it possible to automatically
     analyze even SEM images that were difficult to
     distinguish just with colors and brightness.

Nanostructure analysis using cutting edge technology

 • Analysis of crystal structure and microstructural
     characterization atatomistic level using world-class
     Infrastructure including synchrotron radiation XRD/XAS
     beam-line and Cs-Corrected TEM.
 • Nanoscale characterization of phase transformation
     during heat treatment and nanoscale mechanisms at
     solid-liquid interfaces and high-temperature
     gas phase reaction with high-temperature in-situ
     synchrotron radiationXRD and in-situ TEM system.
